Anyone have a schematic for the blower motor? The service manual doesn't have one. Thanks

What year truck. Heaters were an option 68 and earlier. Diagram may not be in main harness wiring diagram. I know FOR my 66 the heater electrical shows elsewhere in FSM.

Must have been some sort of supplemental manual for options. If its anything like my 66 it is a very basic wiring schematic. :thinking :thinking

Here's what I have for 1968. The picture isn't clear but I can generally sort it. Heater switch is in the upper right quadrant.

I want to reach out to you guys on the Heaters for 61-68, we have a discussion going as well on the wiring.
If anybody has a 61-64 with a heater, I'm looking for verification if the feed wire from the switch actually goes to the Fuel gauge voltage limiter or if it goes to the wiper switch.
Being that the heaters were accessories in 61-68 there are no wiring diagrams for them for 61-64, if you read through our thread you'll see why. I created some diagrams, but will need some actual verification from a truck.

Diagram is now corrected.

The heater draws power from the wiper switch

To be more accurate, the BLOWER (fan) draws power from the wiper switch. That's why there is a B on the knob and not an H. It will operate regardless whether the heater core is hot or cold.

Ok, based on your response and one other, it appears this is where it should be connected.
Thanks Bud.
